(a) In the upper layers of the atmosphere, a layer of ozone is formed, which gets depleted due to chloro fluoro carbons and creates a hole called ozone hole.

(b) Ozone hole is found above Antartica, over the North pole.

(c) UV radiation will reach the earth and cause diseases like - cancer, reduce immunity and reduce crop yield.

The ozone layer present in the stratosphere acts as a protective shield. It saves the earth from the harmful ultraviolet rays of the sun. The compounds containing CFCs (chlorofluorocarbons) are mainly responsible for ozone layer depletion as these compounds react with ozone in the presence of ultraviolet rays to form oxygen molecule and thus, destroying ozone.
